By inspecting the running processes I determined that queue and channel processes sometimes hung on to garbage. Erlang's gc is per-process and triggered by process reduction counts, which means an idle process will never perform a gc. This explains the behaviour - the publisher channel goes idle when channel flow control is activated and the queue process goes idle once all messages have been drained from it. Hibernating idle processes forces a gc, as well as generally reducing memory consumption. Currently only channel and queue processes are hibernating, since these are the only two that seemed to be causing problems in my tests. We may want to extend hibernation to other processes in the future.

It should only do that when it has just finished handling the messages given to it by the proxy in response to a previous request, and not after handling a direct message.

The fix is to adjust the timeout based on the total workload. Alternatively we could not have any timeout at all, but that is bad Erlang style since a small error somewhere could result in stuck processes. I moved the parallelisation - and hence timeout modulation - from the channel into the amqqueue module, changing the API in the process - commit, rollback and notify_down now all operate on lists of QPids (and I've renamed the functions to make that clear). The alternative would have been to add Timeout params to these three functions, but I reckon the API is cleaner this way, particularly considering that rollback doesn't actually do a call - it does a cast and hence doesn't require a timeout - so in the alternative API we'd either have to expose that fact indirectly by not having a Timeout param, or have a bogus Timeout param, neither of which is particularly appealing. I considered making the functions take sets instead of lists, since that's what the channel code produces, plus sets have a more efficient length operation. However, API-wise I reckon lists are nicer, plus it means I can give a more precise type to dialyzer - sets would be opaque and non-polymorphic.
